SUMMARY

 

The in sacco experiment was conducted on 2 Red Sindhi cows installed T-cannula to evaluate degradability potential of dry matter and crude protein of soybean meal and peanut cake treated at different temperature and time in the rumen. The incubation periods in rumen were 12 and 24 hours. The degradability of each material was assessed in five treatments (four with heat treatments and one without heat treatment) with two replicas. The samples were put into rumen at 8 am and 8 pm and simultaneously taken out at 8 am next day. Each material was performed on two different cows at the same time. After removed from rumen, samples were soaked immediately in ice to limit the growth of microorganisms and washed under running water tap until the washing water was clear. All samples were dried at 600C and then analyzed for crude protein content. Results indicated that soybean meal treated at 1250C - 90 minutes gave the best undegradable dry matter (59.3%) and undegradable protein (41.9%) after 24 hours incubation in the rumen. While, peanut cake showed the best results on undegradable dry matter (59.5%) and undegradable protein (47.1%) with heat treatment at 1250C - 60 minutes.
